Abstract

A medical respirator relates to the technical field of medical apparatus and comprises a sleeve, an air inlet tube, an air exhaust tube, a sleeve cover, a handle, a piston, and a limit bolt. The medical respirator is characterized in that the outer wall of the sleeve is provided with scale marks, the front end of the sleeve is fixedly connected with the air inlet tube and the air exhaust tube respectively, the cavity of the sleeve is communicated with the air inlet tube and the air exhaust tube, a one-way air inlet valve and a one-way exhaust valve are respectively disposed on the air inlet tube and the air exhaust tube, the rear end of the sleeve is connected with the sleeve cover in a threaded manner, the front end of the T-shaped handle penetrates through a central hole on the sleeve cover and is then connected with the piston in the sleeve, the limit bolt provided with a hand wheel at the outer end is threadingly connected with the sleeve cover near the central hole, and a limit board is connected to the front end of the limit bolt. The medical respirator has the advantages that amount of air is determined accurately according to weight of a patient, accurate once air amount is achieved, problems caused by inaccurate air amount during long-term use can be avoided, and evident air amount change due to difference of operators can be avoided.

Description

The medical respiration device

Technical field: this utility model relates to the medical apparatus technical field, specifically a kind of medical respiration device.

Background technology: well-known, the medical respiration device is urgent rescue and the assisted respiartion equipment that is used for the critical patient clinically.The machine of breathing no more and need assisted respiartion or because of have a power failure, under the situation such as respirator fault or on-the-spot interim rescue, simply respirator just becomes the only resource that carries out artificial ventilation to patient.Existing simply respirator mainly is divided into adult and two kinds of children, and is no matter the sort of, and its primary structure is exactly that two valves (air inlet, give vent to anger) rubber bulb of adding a sub-elliptical shape is formed, and mediates rubber bulb through the medical worker with hands during use and makes patient obtain to ventilate.Not enough below it exists: patient body weight is different; Required once suction gives amount also different; And existing respiratory organ has no capacity control device, and ventilation is grasped by the operator by rule of thumb, so ventilation is extremely inaccurate; In a short time still can, prolonged application then can be because of the too much or very few crisis patient of ventilation life; In addition, operator's hand-type varies, and can not guarantee ventilation accurately, pushes the dynamics difference at every turn, gives tolerance also different, same patient, and same breathing bag is used by different medical personnel, gives tolerance all inequality, influences patient's rescued effect.

Summary of the invention: the purpose of this utility model is to overcome above-mentioned deficiency, and a kind of medical respiration device that can guarantee accurate ventilation is provided.

The purpose of this utility model is achieved in that this medical respiration device is made up of sleeve, air inlet pipe, exhaustor, cover, handle, piston, spacing screw rod; The barrel forward end that outer wall is provided with scale mark connects fixing air inlet pipe and the exhaustor that communicates with barrel bore respectively, air inlet pipe and be respectively equipped with breather cheek valve and one-way exhaust valve above the exhaustor; The sleeve rear end cover that is being threaded; " T " shape handle front end pass behind the centre bore above the cover with sleeve in piston be fixedly linked; Be provided with the spacing screw rod of handwheel near the outer end that is being threaded near the cover the centre bore, spacing screw front end is connected with limiting plate.

During use; Air inlet pipe links to each other with oxygen hose, and exhaustor links to each other with tracheal intubation, according to patient's body weight; The rotary stopper screw rod makes the limiting plate of spacing screw rod lower end arrive the corresponding body weight scale mark of patient place, and what drawing handle once was this body weight patient then once gives tolerance.

The advantage of this utility model: can accurately confirm to tolerance that once accurate to tolerance, the problem brought because of ventilation is inaccurate can not appear in life-time service according to patient's body weight, ventilation can be because of operator's difference significant change.

Description of drawings: accompanying drawing 1 is the structure chart of this utility model.

The specific embodiment: describe in further detail below in conjunction with 1 pair of this utility model of accompanying drawing: this medical respiration device is made up of sleeve 1, air inlet pipe 2, exhaustor 3, cover 4, handle 5, piston 6, spacing screw rod 7; Sleeve 1 front end that outer wall is provided with scale mark connects fixing the air inlet pipe 2 and exhaustor 3 that communicates with sleeve 1 inner chamber respectively, air inlet pipe 2 be respectively equipped with breather cheek valve 8 and one-way exhaust valve 9 above the exhaustor 3; The sleeve rear end cover 4 that is being threaded; " T " shape handle 5 front ends are fixedly linked with sleeve 1 interior piston 6 after passing the centre bore above the cover 4; Be provided with the spacing screw rod 7 of handwheel 10 near the outer end that is being threaded near the cover the centre bore 4, spacing screw rod 7 front ends are connected with limiting plate 11.
